Hello @mrneilypops!
NodeBB plans range from $35 to $100, depending on the feature set.
$75 and up plans give you advantages like custom DNS forwarding (so you can use something like mypersonaldomain.com instead of myapp.nodebb.com) and daily backups. All plans come with use of the support ticket system, so you can reach us for support for individual instances.
If you have any other questions, please give us a shout at sales@nodebb.org
